Lush is a Lisp dialect with extensions for object-oriented and array-oriented programming. It is intended as a programming environment for prototyping numerically intensive applications. Unlike alternatives like Python or SciLab, Lush is designed for easy integration of existing C/C++/Fortran codes.

The libjit library implements just-in-time compilation
functionality. Unlike other JITs, this one is designed
to be independent of any particular virtual machine
bytecode format or language. Currently, libjit is
used as the JIT backend for the DotGNU
Portable.NET project (in addition to its default CVM
backend). However, the hope is that other Free
Software projects can use this library rather than
spending large amounts of time writing their own
JIT from scratch.

Mistletoe is a JUnit extension intended for integration testing. In technical terms, it is a JUnit test suite runner presenting the test results via HTTP as a Web page. Mistletoe, when incorporated within an application, will help diagnose integration issues. For example, an application that runs perfectly in the developer's environment may not run properly in the production environment due to configuration errors and connectivity issues. Instead of perusing log files, or looking at stack traces, mistletoe will run a user-specified series of tests and present the results in the form of a Web page served by the application itself. Since the tests are run within the context of the deployed application, given an appropriate test suite, you can home in on integration problems quickly and conveniently.

CCNx is a networking system which replaces named hosts with named
content as the primary abstraction. It is sponsored by the Palo Alto
Research Center (PARC) and is based upon the PARC Content-Centric
Networking (CCN) architecture.

SoCLib is a library of pluggable SystemC cycle-accurate and transaction-level components. The library contains many types of models: processor cores (MIPS32, PPC405, ARM-v6k, Nios2, MicroBlaze, lm32, etc.), memory types, devices (block device, UART, frame buffer, etc.) and network-on-chip models. SoCLib can be used to create a complete system-on-chip hardware design, as well as for testing and evaluating embedded operating systems and applications. NetBSD, MutekH, and other dedicated systems are ported to the SoCLib hardware simulator. A Linux port is an ongoing project.

Opticks is similar to commercial tools like ERDAS IMAGINE, RemoteView, ENVI, or SOCET GXP. Unlike other competing tools, you can add capability to Opticks by creating extensions. It supports the following file formats: NITF 2.0/2.1, GeoTIFF, ENVI, ASPAM/PAR, CGM, DTED, Generic RAW, ESRI Shapefile, HDF5, AVI, MPEG, JPEG, GIF, PNG, and BMP. It can zoom, pan, or rotate spatially large datasets. It can quickly layer GIS features, annotations, results, and other information over your data to provide context. It has many image display controls such as colormap, histogram, transparency, etc. Support for datasets larger than four gigabytes. Analysts can quickly combine steps using graphical wizards. Support for processing data in its native interleave of BIP, BSQ, or BIL. Extensions can add new processing algorithms, file formats, visualizations of the data, or data types.

OpenCAN is a software platform for interacting with various Controller Area Network (CAN or CANbus) devices. It provides an abstract C++ interface that can be used to control CAN devices. Support for specific devices can be written as plugins, and then loaded through a simple API call. Each component is cross-platform, enabling the efficient development of CAN software on Windows, Linux, and Mac OS X.
